Flammulated Owl (Otus flammeolus) population and habitat inventory at its northern range limit in the Southern Interior of British Columbia

Abstract

Flammulated Owl (Otus flammeolus) ecology at the northern limit of its range (southern interior of British Columbia) necessitates that inventory data include replicated sampling throughout and between breeding seasons for accurate population and habitat assessment. Auditory census and nest surveys must be linked to assess habitat suitability; census alone can only indicate habitat capability through documentation of presence or absence of Flammulated Owls. Standardization of comprehensive census and nest surveys can provide multi-year population data for landscape management plans. Trend data may serve as a measure of recruitment and help to identify source habitats for retention in management plans.
